<p>Apparatus for measuring the gravimetric fuel consumption of a liquid-fuel burning engine comprises a vessel (10) which is connectable with a source of liquid fuel and which is also connectable with the fuel intake of an engine, and a body (18) capable of floating in the vessel (10) the cross-sectional areas of the vessel and body in horizontal planes have a precise relationship to one another. The body (18) has an upward extension or stem (19) loosely carrying a load weight (29) which can seat on an abutment (31) when the body (18) falls below a given level. Means such as strips (33, 331) secured to the stem (19) co-operating with photocells (34, 35) are provided to generate a first signal when the body (18) falls to the given level and to generate a second signal when the body falls below said level, corresponding to the consumption of a weight of fuel directly related to the weight of the load weight (29).</p> |
